The AAB-II (Analog Amplifier Box) is an analog amplifier housing accommodating eight 5B modules. The wide range of 5B modules provides for the solution of most specific measuring tasks. The 5B modules allow potential free measurement, which is essential for many applications. When incorporated in two 5 1/4" bays of a PC and connected to a PC-measuring card, the AAB-II represents a powerful instrument for the acquisition of measured data.

When combined with a USB data acquisition system from BMC Messsysteme GmbH, the AAB-II serves as a mobile measuring system, which can be used with any laptop. It can also be used as a stand-alone auxiliary device for measuring devices of all kinds.

The amplifier chassis is equipped with eight 5pin input connectors. The power supply is 5V or 9-40V DC. The pin assignment of the module backplane incorporated in the AAB-II corresponds with those of the 5B modules of Burr-Brown and Analog Devices, Inc., however, an additional 0EXC pin has been introduced. Due to the electrical isolation of the modules, hum- and ground loops - often inevitable in large measuring set-ups - can be avoided.

Measurements can be effected on various potentials. The potential deviations, however, should not exceed 60V DC (according to VDE, Association of German Electrical Engineers). The outputs share the same output ground potential.

Optionally available is a cable kit AAB-II-KAPC for the internal PC-cabling of the AAB-II and various power supplies depending on the load.

Please note: As a phase-out model this product is only available in limited quantities! A substitute will be released soon.
